This was always a nice way to do the Oracle RDBMS engine. I am a bit surprised
that GI does not allow for this.
BTW, it is not about tolerating downtime, it’s about making the PSU deploy
easier and safer. Less down time is too nice because I don’t much like being
up Sunday at 5am pushing out patches. I have always like to do as much as my
work in the prep side and less during the actual deploy. Even if it means
overall more time to do the project.
Lastly I agree that if this is not supported by oracle and no one else is doing
this, not sure I want to be the first. I will open a service request with
oracle just for the heck of it and see what they have to say about this.
Thanks Martin and Justin!

I wouldn't suggest you do it either. I've never heard of anyone installing
multiple grid homes, and it's probably not even supported. If this is a
production system, the last thing you want to do is build an unsupported
configuration. Keeping the database available during patching is what RAC is
all about. If you can't tolerate the short amount of downtime a PSU requires,
you should already be running it.

Thanks Martin,
I still want to try to go forward with this idea. It might be a little more
complex than just a shutdown, rename the grid home folder and start backup.
But if I can figure out all that needs to be done, this will be a very nice way
of pushing out PSU patches. And makes a (if needed) back-out a bit easier too.
Besides looking into the root*.sh scripts, anything else you think might be a
“show stopper”?

please don't do this.
an upgrade between patch sets might change more than only binaries. it's likely
(even I have not checked) some internal resources are changed.
If you don't run the proper root*.sh scripts, you might face very strange
results somewhere in the future.
